road, Rnshcllne, and ERNEST B.,WHINNERAH,

builder, of. 10 Brook street, Fallowfield, Manchester, in the county of LancastenfEngland,

, subjects of theQueen of Great Britain, have invented-a new andusefnl Improvementin as now generally used the water isallo'wed' 30' to pass to the carbid or chemical chamber in and Relating to Acetylene-Gas Lamps for following is a specification; p

Our invention relates toimprovements .in and relating to acetylene-gas lamps for cycles; carriages,.or other analogous uses. The objects of. our invention are; first, to

gas may be regularly generated and a regular emi'ssicnthereof at the burner, (thus when the gas is ignited 'a steady light'may be pro.- ducedat the bnrner;)'secondly, to provide an arrangement in connection with the burner whereby the thoroughfare may always be maintained open, so as to allow of thefree exit of gas asgenerated V It is well known that in acetylene-gaslamps.

- irregular quan-tities, whereby "gas is irregu- .larlygelierated, consequently affecting the. vlight or flame at the burner where the gas is ignited; also, when the gasis turned ofi or the light is turned out a deposit of hard matter is formedvet the burner which obstructs the passage. A pricker or instrument is usually employed for .the purpose 10fremoving the v deposit. w This operation is often difiicult and tedious, havingxto be performed under dml-i [:cnlt circumstances, such as trimming the burner during the darkness-of night;

- In ordei' that ourjnventionmay be clearly 1 comprehended, we have hereuntoennexed a 45 sheet of drawings illustrating our-invention,

like letters of reference indicating likeparts.-

Fignre 1 is an elevation ofa cycle-19.1111),-

part insectio'nin "order to show'the application of'our invention thereto. Fig. 2 is a plan "50 showing the upper part of Fig.'1'- that i s,;thei

pinion and spindle in the water-chamber.

the water-chamber a a spindleb, which passes the lower part of the water-chamher wand into sition'by means of a fixed guide-piece g, fixed at the inside of the water-chamber. (See Fig. '2.) The said rack-'piecefengageswith a correspondingly toothed pinion-wheel h, which is-supported by a' spindle i, providedwith. a

stop-piece v. at the side of chamber-a, sothat 'whenj is turned 4: may come in contact with *v' and limit rotation of h; consequently the left of valve e.

Within thehollow stem k we employs wire piece or pricker 0, which" passes through the thoroughfare of the stem to or near the outer upper extremity of the burner land is threaded piece s. by means of a-conn'ecting piece or spindle t, which piece t when the screws issuitably turned travels toward the stein 1c and covers or closes .the entrance of the thoroughfare in the stem and situate within the carbid-chamber. When this operation occurs,the wire piece 0 isconsequently' pushed through a tube orthoroughfare c, situate at or terminates-within the carbidcr chemical" chain-her d, the construction or arrangement knob or turning-piece 3'. We provide the. "knob "with a stop-piece 1)." We also provide a According to our invention we employ insuitably connected at its other end to a screw-.1

'iforward and the end 0' is caused to pass through or out of the burner, and accordingly as the screw-threaded piece sis turned in direction to the right orQto' the left. hand the (wire 0 may be pushed through or withdrawn from the burner l. Thus any deposit whichmaybe situate over the orifice at the outside ofv the burner may be removed, and a fre'ad- 1 mission ofgas is allowed to pass through the same, the removal of which-his an important 1 object to be attained by this our invention. When the spindle b is actuated or the coni'cal piece 6 raised, as shown in dotted lines, Fig. 1, so as to admit water to the chamber d, the conical form of the piece e allows more "or less in quantity to pass through the thorv seat at entrance to tube 0, so as to allow only defined quantities of waterto pass to chamher d.

We claim as our invention- 1. In an acetylenergas lamp, the combination with the watenand carbid chambe rs having acommnnicating passage between them,' of a valve for closing said'passage, a rack car-' ried by the valve and located within the waoer-chamber, a pinion meshing with the rack,

also located within the water-chamber, means arranged at one side of the lamp-body for rotating the pinion to cause the rack and valve to move up and down for the purpose specifled,- and a wire or spindle securedto the nn-' derside of the valve and depending into the 'carbid-chamher for conducting the water thereinto.

2. In an acetylene-gas lamp, the combination with the water and c'arbid chambers'having a communicating passage between them, of a conical valve for closing said passage, a rack carried by the valve, a pinion meshing with said rack, for raising and lowering-the same for the purpose'smecified, a thumb-but ton located outside the lamp-body and secured to the pinion for operating the same, means for locking said button in different positions to control the seating. of the valve, and a spindie secured to the apex of the valve and depending into the carbid-chamber for conducting the water thereinto, substantially as (le scribed.

3. In an acetylene-gas lamp, the combina-' tion with the water and-carbid chambers one located directly above the other and having a tubular connection between them, a conical valve for closing said tubular connection,

a rack carriedby the valve and located'within'the water-chamber, a guide for said rack, a pinion meshing with said: rack also located within the water-chamber, a button located "at one'side of the lamp and having a connection with the pinion for rotating the same, means for locking said button in different positions to control the seating of the valve, and

a spindle secured to the apex of the valve and depending into the carbid-chamber for conducting the water thereinto, substantially as described. Dated this 23d day of January, 1899.
